High Performance Digital Mass Flow Meters and Controllers

Sierra Instruments 100 Series family of mass flow controllers are one of our finest technical achievements in over 35 years in the mass flow instrumentation business. Our 100 Series is designed so the physics are correct! Our 100 Series Premium Digital family is made up of our flagship Smart-Trak® Model 100 , our highly engineered ultra-low flow solution Micro-Trak™ Model 101 and our NEMA 6 & IP67 industrial MFC, the Max-Trak™ Model 180.

Excellent accuracy and repeatability coupled with unsurpassed instrument stability result from a patented, inherently linear design,
advanced platinum sensor technology, and a valve that is strong, flexible and forgiving. Our 100 Series family of instruments has raised
the bar and set a higher standard in the Performance MFC marketplace.

Smart-Trak is our highest performance MFC and is considered one of the finest MFC`s in the world. Smart-Trak is the culmination of a massive three year development effort that has defined a new breed of "Performance MFC".
Smart-Trak is designed so the physics are correct! Excellent accuracy and reliability coupled with unsurpassed instrument stability result from a patented, inherently linear design, advanced platinum sensor technology, and a valve that is strong, flexible and forgiving. Smart-Trak controls gas mass flow from Smart-Trak features Dial-A-Gas® Multiple Gas capability for true digital performance in many gases with the same unit. The Model C100 can be used with any clean gas including mixtures, toxics, corrosives, and combustibles. The unique pilot module replaces expensive control/readout electronics and is available mounted to the face of the instrument or in a convenient hand-held version.
